CROSS FOR GAS MAINS OR PIPES.

SPECIFICATION forming part of Letters Patent No. 408,826, dated August13, 1889.

Application filed April 12, 1889. Serial No. 307,017- (No model.)

To aZZ whom it may concern:

Be it known that I, JAMES C. OONROY, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inCrosses for Gas Mains or Pipes for Distribution of Gas, Water, Steam,&c., of which the following, together with the accompanying drawings, isa speciio fication sufficiently full, clear, andexact to enable personsskilled in the art to which this invention appertains to make and usethe same.

The object of my present invention is to provide a cross for theintersection of gas mains or distrilniting-pipes in which the flow ofthe gas through either of the respective pipes will not be deflected orinterrupted by the flow in the other channel or cross-pipe by 2c reasonof more rapid fioW in one than the other, while at the same timefacility is afforded for the free passage of gas from one pipe to theother for equalizing the pressures in the system of distributing-mains.These objects I attain by a cross such as herein shown and described.

In the drawings, Figure 1 is a plan view of my improved cross. Fig. 2 isa horizontal section at line o c. Fig. 3 is a vertical sec- ,0 tion atline 10 to. Fig. 4: is a vertical section at line 00 m, and Fig. 5 is avertical section at line 3 y.

The shell or body 0 of the cross is preferably of globular form, withpipe-connecting 3 5 branches 1, 2, 3, and 4 projecting therefrom at therespective sides. The passage A extends through the body in onedirection, and the passage B extends through the body in crossdirectionto the passage A. \Vithin the globular portion or center of the bodythese two passages are separated and defined by a partition or diaphragmD, the circumference of which joins the globular shell and divides theinternal space, substantially as shown,

and which serves to deflect and direct the 5 currents orflow of gasthrough the respective passages A and IS, and prevents the flow in onepassage from interfering with or obstructing the flow through the otherpassage or cross-channel. A11 opening or hole F is formed through thecenter partition D, so that equal pressure will be maintained within thetwo passages A and B.

The ends of the connecting branches can be fitted with bolting-flanges,socket-hubs, or screw-threads, or with any other required kind offitting for matching and attaching the end of the gas mains or pipingwhereon the cross is to be used.

By the use of crosses such as above described 6: at the junction ofmains in a gas-distributin g system a more uniform, constant, andregular fiow and pressure are insured throughout the district, as strongconsumption and flow in any particular main will not tend to cut off orexhaust the flow in pipes or mains crossing the same.

I claim as my invention to be secured by Letters Patent- 1. A couplingfor the junction of gas mains and pipes having a perforated partition inthe interior thereof defining the respective passages froin the severalconnecting branches at the position where said passages cross eachother, as and for the purpose set forth.

2. The within-described cross for pipes or gas-distribu ting mains,consisting of the body or she'll O, provided with the crossed passages Aand B, separated from each other by a partition D, and an opening F,connecting said So passages through the partition, all substantially asand for the purpose set forth.

fitness my hand this 5th day of April, A.

JAMES C CONROY.
